All this happen about ten years ago, What I heard was that the 3.3 turbo engine was removed for a rebuild, then owner didn't have the money to finish the engine, Then the 965 was sold car to my bother less drive train, I believe the original turbo engine was sold by that person later on, At the time my brother had a 93 3.6 NA, and he was planning on turbo charging it , then my brother lost interest and didn't have the money for the build also, I'm gonna try to find the original motor, and see if the buyer is will to sell it, and trade for the 3.6 NA engine
